Ok, this is the project: it is a shipping container house built with 6 40" and one 20" containers.




And here are 2 screenshots from Cura slicer where you can see th whole model (scaled down to 10% but there is an issue somewhere between SH3D obj export and Cura obj import) and a cut where you can see how it looks inside the model.




I used 3 boxes to fill the whole building.
For the export I selected only the building without the exterior but with all the interior.

As I allready mentioned, I have to wait with printing this project until a customer project is printed and delivered.
